To all 2071,0722, it may concern:

Be it known that I, CARL MARIA PIEL- STICKER, a subject of the Queen ofGreat Britain, residing at London, in the county of Middlesex andKingdom of England, and FRIEDRICH C. G. MULLER, a subject of the King ofPrussia, residing at Brandenburgon-the-Havel, in the Kingdom of Prussiaand Empire of Germany, have invented certain new and useful Improvementsin the Production of Steel (and other metal) Wire, Plates, rods, Bars,&c., and in Apparatus connected therewitlnof which the following is aspecification.

This invention relates to an improvement in an apparatus for theproduction of steel (and other metal) rods, bars,wire, plates, &c., andis a modification of the apparatus described in an application forLetters Patent of the United States No. 122,577, filed by us March 1,1884. According to this latter pro cess rods of indefinite length wereproduced direct from the molten metal by causing it to enter at one endof a fixed cooling tube and drawing it out, when solidified, at theother end. The rod had therefore to find its passage through the wholelength of the cooling tube, and on account of the resulting frictionthere existed the danger of the rod breaking off while passing throughthe cooling-tube. In this our improved apparatus we entirely obviatethis danger by dividing the casting or cooling tube into two partslengthwise, casting the molten metal into this mold, and then movingforward the lower portion of the mold itself, which at the same timecarries forward the solidified rod. In order to make the operation acontinuous one the cooling or casting mold is of circular form insteadof being of a straight line.

In the accompanying drawings, Figurel is an elevation of my apparatus.Fig. 2 is an end view,partly in section. Fig. 3 is an enlarged view ofthe top part of the apparatus as shown in Fig. 1. Fig. 4 is a plan viewthereof; and Fig. 5 is an end View of the portion shown in detail inFigs. 3 and 4.

Similar letters denote like parts.

Our improved apparatus consists of adrum or wheel, A, made of iron orsteel, mounted on the horizontal axis B, and rotating inbearings formedin the upright supports O, the diameter of the drum being, say, threefeet, and the width of the periphery being, say, six inches or more. Thedrum A is made hollow in order to cool the periphery or face of thewheel, cold water entering at one end, a, of the axis through pipesconnected with the hollow axis, and the heated water escaping at theother end, I), of the axis. In the middle of the face (I of the drum andround the entire circumference runs a groove, :0, of such section as therod to be cast is to represent.

The edge of the wheel is beveled, and its face accurately inclosed byasegment,D, forming a semicircle, the face of the wheel and the concaveside of the semicircular segment both being turned absolutely true. Thesemicircular segment is also made hollow in grder to keep the concavesurface cool, cold water entering at e, and the heated water escapingatf. In order to protect the inner or concave side of the semicircularsegment still further against the action of the molten metal a groove,y, is provided for, opposite to and of the same width as the groove asin the circumference of the drum, the former groove, 3 being well filledwith refractory material; or a groove may also be formedin the concavesurface or" the semicircular segment corre sponding with the groove inthe face of the wheel, and both grooves together may form the section ofthe rod to be cast; but the face of the segment is usually smooth andunbroken, whether protected by refractory ma-' terial or not, and whenrods of a square or angular section are to be produced, it serves merelyto close the groove in the periphery of the drum. hen, however-as, forinstance, in making round bars or bars otherwise curv'ed in section-theface of the segment is grooved as well as the periphery of the drum,then both the grooves may be lined with refractory material.

The upper part of the semicircular-1x segment D is formed with anopening, E, preferably rectangular in shape. This opening extends fromthe exterior of the segment through to the periphery of the drum A, andis fitted with a two-part block, G G, of refractory material. Oneportion of this block is provided with a neck, 9, and the other portionis correspondingly recessed at g to receix e it, the two parts whenunited forming a block completely filling the aperture E, which saidblock is perforated vertically at H, said aperture passing through thetelescopic joint just described. Lugs are secured to the upper block, towhich the hand-lever is pivoted and by means of which the upper blockcan be adjusted vertically to meet the spout of the pouring-ladle. Thevertical channel H communicates with the groove 00 in the face of thedrum A, through which the molten metal is conveyed through the block GG.

Immediately in front of the rectangular opening are two eyes or bosses,L, through which the spindle M passes, resting in bearings N in thevertical supports (1, the segment D being in this manner hung on to thespindle M. Between the two eyes or bosses is placed a box, R, as areceptacle for lubri eating material, a narrow slit or opening beingformed in the under side of the box for the lubricant to fall on theface of the drum A. The outer faceplate of the box It is provided with ashort projection, r, going into the groove :0, just clearing the sides,preventing the metal from escaping in the wrong direction.

S is a spring connected at one end with the foot of the semicircularsegment and at the other end with a screw, P, passing through the footof the upright supports, through which the semicircular segment is madeto .-adjust itself to the face of the drum A when this latter rotates,the screw serving to regulate the relative positions of the wheel andsemicircular segment to each other.

Ve lay most particular stress upon the manner in which the segment D ismade to inclose the face of the drum A by hanging freely upon thespindle M, and upon the adjustment between the face of the drum A andthe semicircular segment D by means of the spring S and set-screw P,which, while it permits to inclose the surface of the drum carrying thegroove or movable casting-mold :0 so accurately that, when rotating, nometal poured in the groove can escape through the joint formed at thecontact of the face of the drum A with the concave surface of thesemicircular segment D, yet, on account of the elastic action of thespring, allows the drum freely to rotate, without causing undue wear andtear of the surfaces.

.Motion is imparted to the pinion W from thepulleyVupon the same shaft.Thispinion gearing with the spur-wheel T causes the drum A to rotate.

A casting-ladle on wheels may be run on rails right over the verticalchannel H in the refractory block G G, or the channel may be directlyconnected with a furnace containing the molten metal.

At the beginning of an operation water is made to circulate in the bodyof the drum A, as well as through the semicircularsegment D. The groove:0 in the face of the drum is temporarily closed with some fire-claywhere the inclosing semicircular segment ends; The metal is then pouredthrough the channel H of the refractory block G G into the groove .10 ofthe drum A, and, after waiting, say, a minute, the drum is made torotate. The rod to be cast issues at O, at a tangent to the periphery ofthe drum, and while still red-hot is passed between rolls placed infront, and is so shaped and compressed.

We point it out as a matter of great importance in this invention thatthe rod issues at a tangent to the circumference of the drum and notunder any angle, which not only greatly facilitates the passing of therod subsequently between the rolls, but also, by obviating any strain ortwist in the still soft metal, removes any danger (especially whendealing with rods of small sections) of the latter breaking or tearingoff.

Instead of producing only one rod at a time, two or more may be castsimultaneously by providing two or more grooves on the face of the drumA.

When the production of plates or bars of a flat section is intended, thechannel H in the refractory block G G forms a slit, extending across thewidth of he face of the drum, of such width as the plate or bar is torepresent.

The word rod throughout the whole of this specification is to stand forsteel (or other metal) of any section that can be dealt with by thisprocess and apparatus.

Having now fully described our invention, what we claim, and desire tosecure by Letters Patent of the United States, is
